Function g(x) is function f(x) translated 3 units to the left and 2 units down.

Here we know that the function f(x) = (x − 2)³ is transformed to g(x) = (x + 1)³ − 2.

Remember that:

A vertical translation of N units is written as:

g(x) =f(x) + N

if N > 0, the translation is up.

If N < 0, the translation is down.

A horizontal translation of N units is written as:

g(x) =f(x) + N

if N > 0, the translation is left.

If N < 0, the translation is right.

Here we can see that:

g(x) = f(x + 3) - 2

Then we have a translation of 3 units to the right and 2 units downñ.

Answer:

Area = 91 square inches

Step-by-step explanation:

Let

L = length of the rectangle in inches

W = width of rectangle in inches

We are given:
The length of a rectangle is one inch less than twice the width

In math terms this is equivalent to:
L = 2W - 1

he perimeter of the rectangle is 40 in.
The perimeter of the rectangle = 2(L+ W)

So in math terms;
2(L + W) = 40

L + W = 40/2

L + W = 20

Since L = 2W - 1 we can substitute for L in terms of W in the above equation:
L + W = 2W - 1 + W = 3W - 1

Equating it to 20 gives
3W - 1 = 20

Add 1 both sides:
3W = 21

W = 7

Which gives

L = 2W - 1 = 2(7) - 1 = 14 - 1 = 13

So L = 13

The area of the rectangle = L x W

= 13 x 7

= 91 square inches

Answer:

k is 2.5.

Step-by-step explanation:

To find the value of k, we can use the information given about points A and B to find the value of the parameters a and b. Since we know that the curve passes through A (1, 10) and B (4, 80), we can substitute these points into the equation y = ab^x to find the values of a and b.

Starting with point A:

10 = a * b^1

Next, using point B:

80 = a * b^4

We can now use these two equations to find the value of b:

10 = a * b^1

80 = a * b^4

Dividing the second equation by the first equation:

8 = b^3

Taking the cube root of both sides:

b = 2

We can now use either of the two equations to find the value of a:

10 = a * b^1

a = 10/2 = 5

Now that we have found the values of a and b, we can substitute the point C (-1, k) into the equation y = ab^x to find the value of k:

k = 5 * 2^(-1) = 5 * (1/2) = 2.5

So the value of k is 2.5.

Answer:

y = 3x + 10

Step-by-step explanation:

slope intercept form​ is y = mx + b

y - 4 = 3(x+2)

y - 4 = 3x + 6

y = 3x + 10

So, the answer is y = 3x + 10

The required value of y is 8/12 and the sequence is given as 1/2, 7/12, 8/12, 3/4.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Here,
Let the common difference between the values be d = 1/12
Now

Since x in the second term
x = 1/2 + (2- 1 )1/12
x = 7/12

Since y is the third term
So,
y = 1/2 + (3 - 1)d
y = 1/2 + 2/12
y = 1/2 + 1/6
y = 6 + 2/12
y = 8/12

Thus, the required value of y is 8/12 and the sequence is given as 1/2, 7/12, 8/12, 3/4.

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( -3 , -4 )

Let the second point be Q ( 7 , 6 )

By applying standard deviation concept, it can be concluded that all the students had the same score.

The mean is the average of all the scores. It is calculated by adding up all the scores and dividing them by the number of scores.

The standard deviation is a measure of how spread out the scores are. It is calculated by finding the difference between each score and the mean, squaring those differences, finding the average of those squared differences, and then taking the square root of that average.

If all the scores are the same, then the difference between each score and the mean will be 0. This means that the standard deviation will also be 0. Therefore, the correct answer is "all the students had the same score."

At a total price of $2720 for 4 Computers, retailer 2 delivers the best deal based on the listed specials.

Based on the stated sales, we need to figure out the entire cost of 4 computers at each retailer, accounting for any discounts or promotions, in order to determine which store will provide the lowest pricing for 4 Computers.

Let's use the following variables to symbolize the costs and special offers at each retailer:

P1: the price of a single computer in a store 1

P2: the price of a single computer in a store 2

P3: the price of a single computer in a store 3

P4: the price of a single computer in a store 4

D1: discount on one computer at store 1

D2: discount on one computer at store 2

D3: discount on one computer at store 3

D4: discount on one computer at store 4

Then, we may figure the total cost of four computers at each store using the following formulas:

Total cost at store 1 = 4(P1 - D1)

Total cost at store 2 = 4(P2 - D2)

Total cost at store 3 = 4(P3 - D3)

Total cost at store 4 = 4(P4 - D4)

The total cost at each store can then be calculated by plugging in the values from the table as follows:

Store 1: Total cost = 4(950 - 0.2*950) = 3040

Store 2: Total cost = 4(800 - 0.15*800) = 2720

Store 3: Total cost = 4(1100 - 0.25*1100) = 3300

Store 4: Total cost = 4(850 - 0.1*850) = 3060

No, f(x, y) = 3x - 3y^2 is not a harmonic function.

A harmonic function is a twice continuously differentiable function f(x, y) that satisfies the Laplace equation:
                                                                            ∂²f/∂x² + ∂²f/∂y² = 0.

Let's check if f(x, y) = 3x - 3y^2 satisfies the Laplace equation:
∂²f/∂x² = ∂/∂x(3) = 0
∂²f/∂y² = ∂/∂y(-6y) = -6
∂²f/∂x² + ∂²f/∂y² = 0 + (-6) = -6 ≠ 0

Since the Laplace equation is not satisfied, f(x, y) = 3x - 3y^2 is not a harmonic function.
